Crestron MP-AMP30 Media Presentation Audio Amplifier
Media Presentation Audio
Amplifier: MP-AMP30
Introduction
The Crestron
®
MP-AMP30 provides a convenient, low-cost audio amplifier solution
for a variety of applications. A perfect complement to the entire Media Presentation
line from Crestron, it features a compact surface-mountable design that installs
virtually anywhere without requiring an equipment rack. High-efficiency Class D
circuitry delivers 15 Watts per channel to drive one or two pairs of 8-Ohm speakers,
or a single pair of 4-Ohm speakers, making it ideal to support stereo speakers at the
front of a room or mono speakers in the ceiling. Mono-summed operation is enabled
by changing two jumpers on the front panel.
Refined, reliable operation is ensured thanks to pop-free turn-on circuitry and
electronic short-circuit and overload protection. An energy-saving design achieves
optimum efficiency under load, and powers down automatically when no input
signal is detected for more than five minutes, reducing overall power consumption
and heat as part of a green system design. Its extruded aluminum housing is both
attractive and effective at dissipating heat, affording a silent running design without
cooling fans.

Installation and setup of the MP-AMP30 is simple. Detachable output connectors
facilitate the termination of speaker wiring up to 16 gauge. RCA inputs connect
directly to the line output of a video projector or display, audio processor, mixer, or
AV switcher. Rotary controls provide for adjusting the overall speaker volume, as
well as bass and treble. For quiet environments, loudness compensation is employed
by setting the volume control below the center detent position.
